i 2 Claims. The invention relates to improvements in casingconstruction, particularly in casings for en-.

closing boilers, heaters and air conditioning units. More specificallythe invention relates to casings for enclosing automatically firedboilers, heaters and air conditioning units.

In the recent development of the heating and ventilating art, the use ofautomatically fired apparatus has promoted the usaof the room or thespace, in which the heating or air conditioning device is located, forrecreational, living or other purposes and anobject of the presentinvention is to provide, a suitable casing to enclose the device in sucha way as to conceal unsightly, irregular forms and to present anattractive, decorative and comparatively symmetrical appearance.

Casings of thistype are generally bulky and '7 awkward, and areexpensive to ship and to handie, if assembled before shipping, so thatanother object of the invention is to provide a finished casing suchthat it can be assembled at the place where it is to be used, withoutthe use of special -tools or special skill.

parts shall be readily and quickly accessible for,

purposes of service and repair, a further object of the invention is toprovide a casing comprising panels without hinges or catches, supportedin a frameworkof suitable strength 'and rigidity, of which the wallpanels may be separatly, quickly'and easily detached from their positionin the framework without the need of any tools and o'f-which panels, anyone or more may be removed from its position without displacing ordisturbing otherpanels. v

Asit is frequently desirable-to heat insulate heating or airconditioning units, more or less fully, still another object is toprovide a casing of panelled form in which'the panels are domountableand adapted to receive heat insulation of the casing with parts cut awayshowing the 1936, Serial s. 104,121 (01. 220-4) panel construction andthe manner in which the panels are set up in theframework.

Fig. 3 is a fragmentary perspective view showing the casing frameworkfrom the outside at one corner, the parts being disassembled andseparated from each other and some broken I away so as to showconstruction of various framework members.

Figs. 5, 6, '7 and 8 are reduced elevational views of the four sides;namely, end, front, rearand other end, respectively, of 'the'casingpanelling showing the disposition of the panels and-the openings forsmoke pipe and boiler connections.

Fig. 9 is a perspective view showing front, top and one end of a casingadapted for use with an air conditioning unit showing air inlet andoutlet ducts.

In the drawings like reference characters indicate like partsthroughout.

The invention may be described as comprising an enclosing casing open atthe bottom, having atop and side walls and a rigid, adequately strongframework of shaped metal parts held together by screws or bolts, theframework having a rectangular box-like conto and having its partsadapted to receive remo able, abutting, top and side wall panels.

The casing comprises a framework having top and bottom rail members 20and 2| on each of the four sides and corner posts members 22 at the fourcorners. The top and bottom members are joined by suitable top andbottom gusset members 23 and 24, respectively, (Figs. 3 and 4) whichserve not only to join the respective members but also as spacer membersso as to facilitate assembly with the cdrner posts 22 and the top andbottom corner pieces 25 and 26, respectively. The corner posts are setup in the space provided between the rail ends when joined by the gussetmembers and are held in place by means of the top and bottom cornerpieces, the parts being joined together by screws.

It will be noted that each of the various parts, top and bottom rails,corner posts, top and bottom corner piecesand gussets -are allstairdardized for the particular casing and that the parts,

tion so that a minimum of dimculty is experienced in putting theframework'together. This interchangeability'of parts permits theframework to be shipped in knock-down condition and erected on the sitewhere used, around the boiler or heater, and as there are no otherfastening members except small screws or bolts, the whole may be set upwith a small screw driver and wrench so as to provide a strong and rigidstructure.

to the place of use and is conveniently set up around the heater, thebottom rails resting directly upon the floor upon which the heaterstands.

The lower rail member 2| of the framework comprises a Z shaped portion30 and an L shaped portion 3|. One leg of the L shaped portion forms thebottom of the lower member upon which the casing rests, the other legextends vertically upward and forms the outwardly disposed portion 32 ofthe lower member; one leg of the Z shaped portion is fixed by spotwelding or by other fastening means to the inner face of the L shapedportion at its angle so that the web 35 of the Z shaped portionextending horizontally, inwardly and its other leg 361 extendingvertically, upwardly, form, with the remainder of the upwardly extendingpart of the L shaped portion, a channel 38 with which the lower ends ofthe panels, to be described later, interfit freely.

The upper rail framework member 20, comprises a channel shaped portion45 with the channel disposed so as to extend vertically downward and anL shaped portion 4| with one leg spot welded to the channel shapedportion so that the other leg 42 of the L shaped portion extendshorizontally, inwardly and forms an inwardly extending shelf upon whichthe cover panels are supported.

The lower rail members are joined at the corners in spaced relation, soas to permit the corner posts to be fitted into place, by means ofgusset members 24 which are held in position by screws; the upper railmembers are likewise joined at the corners by the gusset members 23.

The vertical corner posts comprise formed metal molding members 22, withoutwardly concaved round corners 46 and flanges 41 extending outwardlyon either side of the corner so as to present outwardly disposed facesin planes perpendicular to each other and in the plane of the outwardlydisposed wall panel faces when in place. These flanges on either sideare bent again inwardly at right angles 48, to the previously mentionedflange faces. The flange faces 48 provide a smooth surface abutment ateither side of the corner posts which abutment lies adjacent to thevertical end panel edges when in place in the casing. The corner postsmade up as described form a rigid, strong corner of the framework.

The corner posts and bottom rails are joined together by means of thebottom corner members 26 which are all provided with holes for theinsertion of screws or bolts by which the parts are held together. Thecorner posts and top rails are joined together in a similar way by meansof suitably shaped top corner members 25 and are also fastened togetherby means of screws. The corner members are made so as to provide asomewhat ornamental finish to the framework.

The wall panel members for the four sides 5|, 52, 53, 54, 55, 56, 51 and58 are: made of sheet metal of suitable gauge and are provided withinwardly extending flanges 6| on the lower edge and on the two verticaledges, the flanges being at right angles to the panel faces. Theseflanges The framework in disassembled state is taken are bent inwardlyonce more at right angles at 52 to the flanges 6|, the flanges 62forming a retaining flange for sheet-form heat insulation ma- Theflanges being omitted from the terial 63. top edge of the panel permitthe insulation material tobe slid into place from the upper end fromwhich. the flanges are. omitted and to be retained in place by theflanges around the other three sides of the panel previously described.This arrangement of parts permits ready renewal or replacement of theinsulation material and the flanges also serve to stiffen and tostrengthen the panel.

The channels in the upper and lower rail members and the flanges SI ofthe panel are made to interfit. The panel dimensions and the upper andlower rail members are proportioned so that the channel 40 in the upperrail member is twice the depth of the channel of the lower rail channelmember 38. The panel members are of a length which equals the length ofthe open space between the upperand lower channel members plus slightlyless than twice the depth of thelower channel 38. The panel is providedwith a louver 6 which also serves as a hand hold. In order to place thepanel in its position in the framework of the casing the upper margin ofthe panel is inserted in the upper rail member channel and raised untilit clears the lower rail member and then the lower margin of the panelis brought into registry with the lower rail channel and dropped intothe place in the lower channel. The side wall panels are all insertedinto position in the same way and in any order desired and any one orall of them may be removed and put into place again at will as requiredWithout the use of any tools at all; Fig. 2

shows'one of the wall panel members being placed in its position.

The top covering panels 10, H and 12 are formed with doubly, inwardlyextending flanges 13 on all four sides and are merely supported by theinwardly extending flanges 42 forming the shelf portion extendinginwardly from the top number of standard sizes of panel members by.

merely providing various suitable lengths of top and bottom railmembers.

The panel members are provided with additional louvers 15 where requiredand with necessary openings 16, l1, l8, l9 and in certain panels whererequired for smoke pipe, controls or observation instruments and inletand outlet connections as shown in Figs. 5, 6, '7 and 8.

The structure fabricated and put together as described herein provides afinished casing for the purpose stated which is shipped in knockdowncondition and is assembled when and where used and which is possessed ofthe required rigidity and strength; which may be put together withoutspecial tools; and of which the panel members may be removedforinspection of the apparatus encased or for other purposes or whichmay be replaced at will without any tools and which may be varied insize by means of varied standard sized panels and rail members; inaddition the form of the casings, and of the panels and framework, aswell as the lack of need to do any material mechanical work on themwhile making the installation permits of decorative finish, painting,baked enamelling or plating to be done on the casings in the knock-downform and to be shipped as a complete article ready to be set up, withgreat economy of storage space, labor and shipping charges.

The casing may be used for air conditionin units, as shown in Fig. 9, bychanging the arrangement of the cover panels to permit connection' withthe intake BI and outlet 92 for the air to be circulated, similarframeworkand side wall panels being used, as are shown in Figs. 1 to 8inclusive, and of a sizetosuit the installation.

.While I have described specific embodiments of the inventionwhich havebeen shownin the drawings, it is to be understood that the invention maybe further modified as'to construction and arrangement of the severalco-operating parts without departing from the spirit or scope of theinvention.
